RadTreeList - how to declare multiple parentKeys/DataKeys?

Hello Kostadin

Thank you so much for the code.  I have it working now.  I was using a UserControl for RadTreeList but for some reason the expand/collapse does not work that way.  So, I extracted the code and inserted it in its place (the way you have it), and it works!  Thank you so very much.

One more small question.  You have a '<ClientEvents OnItemSelected="getSelectedItems" /> in your definition of RadTreeList.  But I don't see a definition.  Can you show me how to write this?  I need to be able to select an item and do something with them.

Thank you

Raka
